Changing Oil

Whatever brand or type you choose the frame and the rest of the truck will give up before the engine does. I think the important thing is to use quality oil and filter and change it at the correct interval. These engines are known for their reliabilty, just read some of the high mileage threads. I choose synthetic with an OEM filter but the previous owner used dino but always changed by the dealer every 4-5k.

 

Thanks for your info
Seems like some use Synthetic 0W20
and some use Synthetic 5W30
Whats Up With That???

 

V6 specifies 5W-30 and the I4 specifies 0W-20.

 

I have read people using 5W-20....whats the dif? Obv I know nearly nothing...

 

The numbers indicate the viscosity of the oil. The first number with the W is how the oil acts when cold, the second when it is hot. Higher the number the thicker the oil is (more viscous).

In a very general sense the lower viscosity the oil the less resistance is provides to the oil pump and potentially other parts of the engine. Some people go with lower numbers in the hopes of improving fuel economy. Mobil did a test showing moving from 40 to 30 cut fuel consumption by 1%. Problem is as you go with lower and lower viscosity oil (thinner oil) it does not provide adequate lubrication to protect the engine.

People in extreme climates (very very hot or very very cold) may find good reasons to use an oil different from the manufacturer recommendations (generally higher numbers in hot places, lower numbers in cold places). And in fact some owners manuals for some cars will indicate you can use a few different oil weights depending on your climate.

All that said I'd recommend running the recommended weight oil for your engine. Toyota designed the engine for a particular weight oil. Don't try to out think them unless your driving conditions are somehow really unusual.

 

Great! Thanks for the breakdown...i live in WI so we hit both sides of the spectrum in regards to hot/cold. That being said, I think just running 5W-30 will be fine year round here from what you explained.

I am doing my recon regarding oil changing as I am approaching my final 'free on at dealership. Fumoto valve also seems like a must for an amateur like me...

Thanks again

 

Delo ftw.

 

Mobile 1

 

Ha ha. Ok. I am sorry. Did that say 75000 miles engine swap oil change

 

no, 5000 mile intervals for the last 75000 miles....

 

I run Castrol high mileage gtx. 5w30

 

Mobile 1 5w-30 @ 5000 miles, I've had engines come apart with expensive oils and cheap oils so don't think it matters to much as long as you change it often.

 

Mobile 1 full synthetic 5w-30 and ome filter,I change it every spring and fall.

 

You must not drive much. Lucky

 

10,000 miles a year or less average.

 

I like Pennzoil platinum ultra, also ran Rotella T6 5w-40 for two changes. As long as you use a quality oil & filter cant go wrong really.

 

No synthetic just regular Pennzoil has worked for me every 3000 miles like clock work while
supercharger the whole way,
